Fellows,

I have:

switch (keyboard_key)
{



	case (vk_up):
// blablabla, break and such things that works

How to write corectly "&&" that will work?

I mean for example:

case (vk_up) && (vk_left):

Do I suspected corectly that one key case should be after than two key cases? Mean

case (vk_up) && (vk_left):
	case (vk_up):

instead of

	case (vk_up):
	case (vk_up) && (vk_left):

Ok, what to do that up and left will give me upleft movement? because up is working and left too...

i belive the && has to be inside the parenthesis as well
'case(vk_up && vk_left)'

[Davve]

keyboard_key is a variable, and a variable can only hold one value so...

if (keyboard_check(vk_up) && keyboard_check(vk_down)) {
	 show_message("You pressed Up and Down at the same time! o.O")
}

I'm afraid you can't use switch here..

EDIT:
Use this if you want 8 direction movement:

x+=keyboard_check(vk_right)*4
x-=keyboard_check(vk_left)*4
y+=keyboard_check(vk_down)*4
y-=keyboard_check(vk_up)*4

Sh&¤%#, I had such suspiction that CASE is not good in this case...

I know that left, right and such has values, but I think IF will be more realiable.

I just was thinking that meybe someone have fixed this that way. Good to know that I was going wrong way before get to far

Thank You for help fellows.

I had this issue once. I fixed it.

Here:

switch *variable name ONLY*
   {
   case *whatever:
   case *whatever else,but same result*:
   Bla bla bla code does stuff
   break
   }
